[PDF] HIGH PERFORMANCE CONCRETE MIXTURES FOR

High performance concrete (HPC) mixtures of different strength characteristics using two types of coarse aggregates were spun in a specially designed spinning machine and tested for strength, differential shrinkage and durability. Low water-cementitious ratio, addition of silica fume for up to 10 percent of the weight of cement and the use of superplasticizers were the characteristics of
